Quite a bit has happened in the past few months since I’ve written anything substantial. With school picking up, it’s hard to write since both activities draw from the same energy source.
Today marks the first time since my knee surgery, nearly a year and a half ago, that I’ve run for seven consecutive days. The last time I ran six days in a row was at the beginning of September, and I felt awful by the end of that streak. From mid-August to the beginning of September, I ran about five or six days in a row and then took the other days on the bike to try to alleviate the completely trashed feeling from running. By the end of September, I had been running about six miles on the days I ran and started to feel more smooth doing it, but I was still pretty beat up.
Part of the beat up feeling was more than likely due to me favoring my non-surgery leg when running. I had been fighting an adductor strain on my right leg that gradually got worse until I was unable to walk without limping. While my left knee felt fine, my right leg hurt just about everywhere. At first, I thought it was just the humidity, but as the summer ended, the problems persisted, and I was forced to stop running at the beginning of October. From then until the beginning of December I spent most of the time on the bike, with a few botched attempts at running once my thigh problems calmed down. However, within the last few weeks I’ve been able to restart running while keeping everything under control. With the introduction of cold weather, it’s a lot easier to run than bike, despite buying warmer clothes to ride in the cold and rain.
At this point, I’m certain that I’ll never feel as good running as I did when I was on my college team. On the team, even on the worst days after a race or hard workout, I still felt light on my feet and able to cruise through a 10-15 mile run without thinking. Today, each step I take is a considerable effort, like I have to drag myself through five or six miles. Comparing how I felt when running on the team with how it feels now reminds me of a passage in Neal Stephenson’s Cryptonomicon. A character in the book compares the power of a bandsaw to other saws and a Vickers machine gun to other firearms:
[T]he most noteworthy thing about the bandsaw was that you could cut anything with it and not only did it do the job quickly and coolly but it didn’t seem to notice that it was doing anything. It wasn’t even aware that a human being was sliding a great big chunk of stuff through it. It never slowed down. Never heated up.
Guns could fire bullets all right, but they kicked back and heated up, got dirty, and jammed eventually. They could fire bullets in other words, but it was a big deal for them, it placed a certain amount of stress on them, and they could not take that stress forever. But the Vickers in the back of this truck was to other guns as the bandsaw was to other saws. The Vickers was water-cooled. It actually had a fucking radiator on it. It had infrastructure, just like the bandsaw, and a whole crew of technicians to fuss over it. But once the damn thing was up and running, it could fire continuously for days as long as people kept scurrying up to it with more belts of ammunition.
Before my surgery and when I was on the team, it was as if I could just go forever and chew through any workout or race, “firing continuously for days.” I never slowed down and rarely heated up. There were limits, of course, but reaching them required hundred mile weeks, punishing pace runs, and draining interval workouts. Like the Vickers, there was also quite the support infrastructure of coaches, trainers, and teammates. But now only running a few miles is “a big deal” for me. It places quite a bit of stress on me, though it is easier than in the late summer. I’m quite sure I’ll have to spend a lot more time on the bike, but maybe I’ll get to the point where I’ll want to run a race.
With respect to school, I’ll be travelling to Stockholm in April to present a paper at RTAS. I’ve been working on several projects related to event detection with accuracy guarantees, which will probably form the basis for my thesis. I also went to RTSS in Washington, DC two weeks ago, but only a few tracks were on wireless sensor networks, but most were about job scheduling and cache replacement policies with the latest multi-core architectures. I’ll also be starting a project with mobile phones with a few other students in our department, which should be interesting. The traditional concept of wireless sensor networks entails small devices with cheap sensors and the processing power of a scientific calculator. However, mobile phones have considerably more power as well as onboard sensors and have more potential for practical applications that people would actually use.
It’s interesting that I spend much of my time writing, creating presentations, and sketching out designs and high-level solutions. About half of my time is actually spent programming. It’s probably a good thing since it gives me a balance between different tasks. Writing papers and creating presentations can be tedious since it can be difficult to cram in months of work into a short paper or presentation. It’s also difficult to create a good balance of high-level descriptions and details to keep people interested but not get confused. When working with a small group of people on a project for a long time, it’s easy to get stuck in a box and not consider things that outsiders would see as obvious. Working with a few other students on my next project should help with this.
It’s when I run into my old teammates that I realize that despite being in the same town and same school that things are really different. One of my teammates got married a few weeks ago and at the wedding, it really hit home that I’m living in a new era. We’re no longer kids. School has taken on a whole new meaning. My relationship with my longtime girlfriend has also taken on a new meaning. Many of the people and the places are the same, but life is different.
